Couple quick questions...
 

Installing a Ms3 in n/a form before bolting up turbo stuff. This is a 2003.

1. I have a GM IAT sensor- just put in in the factory spot before turbo (in air box), then on the exit side of the IC once installed? Just extend the factory wires, right?

2. Vac line- I remember a post showing where to tie in to the intake to get vac/ boost- seem to remember seeing two locations, one for a boost gauge, another for the Ms3. Seems I could just run one tube from the manifold to both the gauge and Ms3, and t off of it for both. Pressure or vac would be the same regardless of the port, no?

3. O2 sensor. Until I install the turbo I was thinking about removing the factory O2 and installing the WB... is this ok? Don't want to add a bung in a downpipe that will be tossed in a month.


Thank you in advance.

1. Yeah
2. Yep
3. You only need the stock O2 sensor if you want to keep the stock ECU. MS + WB is ten time better anyway.

yes
yes, anywhere on the manifold I usually use one of the many rear nipples
yes

Muchas Gracious!
Props for both
